AquaForte Prime UltraSieve III 300µm - Grid Filter

UltraSieve filters are the most reliable pre-filters on the market. This is partly due to the simplicity of the design, with only one moving part. The pre-filter is not self-cleaning, but it is very easy to maintain: simply open the knife valve, after which the dirt can be rinsed away. UltraSieve pre-filters have a stainless steel filter element that never needs to be replaced. Thanks to the triangular stainless steel rods angled at 7°, water falls directly through the screen, while the dirt remains behind. A major advantage of this principle is that the dirt is actually removed from the water circulation.
This has a major influence on water quality, as the dirt can no longer be discharged back into the water.

• The most effective pre-filter for ponds (including swimming ponds)
• Reliable! (only one moving part)
• Stainless steel filter element
• Waste is separated directly from the water circulation
• No noise
• No water loss
• Waste can be recycled 100%
• Easy to maintain
• Ideal for swimming ponds!
• Market leader for over 15 years

How it works

Pond water flows over a removable wall connected to a float, so its height is adjusted automatically. This level adjustment ensures that the amount of water pumped is exactly the same as the amount flowing back into the filter. The water is then directed onto a curved screen located downstream of the removable wall. On this model, the screen consists of hundreds of triangular rods spaced 0.3 mm (300 microns) apart. The rods are slightly inclined: coarse debris is trapped, while the screened water continues on to the main filter.
